Z, also known as the mass number, describes the total number of protons and neutrons in a nucleus.
Depends on the element .
mass number = protons + nuetrons
Looking at a periodic table, you see Al is number 13. It has 13 protons in the nucleus,so to have a total mass number of 24, it must have 11 nuetrons. Mass number = # protons + # nuetrons
mass number = protons + nuetrons
Mass number will help you. Mass number is the total of neutrons and protons.
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
The isotope Germanium -72 has 32 proton, 40 neutrons and 32 electrons. Two other stable isotopes are Ge-70 (38 neutrons) and Ge-74 (42 neutrons) both with the same numbers of protons and electrons as Ge-72 There is also a low percentage stable isotope Ge-73
Answer 1The mass number of a nuclide is the sum of the mass of the protons and neutrons in the nucleus. Protons and Neutrons have a mass of approximately 1 atomic mass unit (electrons are not included since the mass relative to the mass of a proton and neutron is to small to count in the total mass. The atomic number of an atom corresponds to the number of protons in the nucleus, and that is the difference.Answer 2Mass number is the total number of protons and neutrons in the nucleus of an isotope. Atomic number is the total number of protons in the nucleus of each atom of an element.
the total number of protons and neutrons in the nucleus.
The number of protons in the nucleus of each atom of the element.
